title: A case report of primary fibrosarcoma of the liver.
abstract: A 75-year-old woman was admitted to our hospital complaining of right hypochondrial pain. Echo sonography and computed tomography demonstrated a large tumor with irregular internal density in the right lobe of the liver. Angiography revealed a moderately hypervascular tumor. She was treated with transcatheter arterial embolization. Three weeks later, the tumor ruptured. She died of accompanying acute myocardial infarction seven months after the onset of the illness. Autopsy revealed primary fibrosarcoma of the liver. The tumor appearance varied from firm whitish to soft myxomatous. A part of the tumor showed hemorrhagic necrosis. There was no intrahepatic metastasis. The tumor tissue was composed of spindle shaped cells and immunohistochemically stained with vimentin.
